These are just some of the newspaper articles, fliers and other information about the disappearance of Rachel Cooke, nearly 15 years ago.

Williamson County Sheriff Robert Chody is assembling a new investigative team he hopes will help solve the county’s most well-known missing persons case — the disappearance of 19-year-old college student Rachel Cooke in 2002—as well as about 10 unsolved homicide cases.

The crimes date back to 1979, when deputies found a still-unidentified victim in what they call the orange socks case, and the 1988 murder of laundromat owner S.E. Richey, who was attacked in his driveway near the community of Shiloh in what investigators think was a robbery.

In a unique approach, Chody is soliciting help from retired investigators with experience investigating homicides and other major crimes from across Central Texas to voluntarily work the cases. Chody thinks their range of experience with federal, state and local law enforcement agencies could help them see evidence differently than previous detectives or that they may spot something that previous investigators possibly missed.
